Problem Statement

With the new weekly limits it's often necessary to change models and not always use sonnet ( my prefered one ). I've changed all my own agents now to inherit the currently selected model, but there is now a real pitfall here, if I'm on opus and run extensive tasks, weekly limits approach very quickly.

Proposed Solution

In order to avoid, we need a simple but effective logik how to identify on which model you are in a specific chat. If you've multiple windows and chats open the same time, it's possible to forget or mix up. My suggestion is to change the background color to a specific color associated with a specific model selected, e.g. green for haiku, blue for sonnet or black for opus. Similar as you have with your agents, it's very easy but effictive concept.
